The Queensland government is assessing $78 billion worth of significant projects with the potential to create 40,000 jobs.

Deputy Premier Jeff Seeney has told the Major Projects Conference in Brisbane the government has tried to streamline and fast-track approvals processes to encourage development.

He said several key schemes, such as the $1.4 billion Ella Bay resort, $1.6 billion Alpha Coal project and the South of Embley bauxite mine, have been approved since the Liberal National Party (LNP) government took office in March.

Mr Seeney took aim on Thursday at the Federal Government for slowing down some of the process, but said a new bilateral agreement between Queensland and Canberra would help solve the problem.

"That bilateral agreement requires the Commonwealth to adhere to timelines in the approvals process," he told the conference.

"Something that they have been woefully inadequate in doing in the past."

However, he said the government now is actively assessing 35 major schemes.

"Those 35 significant projects together have the potential to generate $78 billion in capital investment and over 40,000 jobs."

Mr Seeney said the government had set up its Royalties for the Regions program to help benefit the communities where the projects are being built.
